Abstract
A series of 1,2-cyclic monoacyl-rac-glycerothiophosphates of cantharidin and its analogues were synthesized in a one-pot procedure in overall yields of 44-55.5% by means of hexae-thylphosphorus triamide, activated by a catalytic amount of iodine, as phosphorylating reagent. Their structures were confirmed by 1H NMR, 31PNMR, IR and elemental analysis.
